ECS Tuning Performance Kevlar-reinforced belts give you that extra peace of mind! Kevlar reinforced belts experience less elongation over time minimizing the amount of belt adjustment needed as well as offering a higher shock and impact resistance compared to OEM style belts.

ECS Tuning Performance Kevlar-reinforced belts have been put through a series of multiple tests:

• Tensile strength
• Elongation
• Hardness
• Temperature and oil resistance per standard JASO E 109-94
• Flex testing per SAE J2432.
